1). Almost all current testing methods cannot be

implemented by hand except by the most dedicated or

desperate testers.

2). Automation encourages projects to re-test more

frequently.

3). Reduce testing costs.

4). Reduce time spent in the testing phase

5). Detect errors early and to raise the quality of the

delivered software.

6). Achieves the repeatability required for valid test

results.

7). Improve test coverage

HI 
 A small doubt u told that in automation detects errors in
early stage  but qtp is not for finding bugs na just for
faster executions..................


Please correct me if any thing wrong (its my opinion)

Benefits of Automated Testing
----------------------------- 
 
Fast:  QuickTest runs tests significantly faster than human 
users.

Reliable:  Tests perform precisely the same operations each 
time they are run, thereby eliminating human error.
 
Repeatable:  You can test how the Web site or application 
reacts after repeated execution of the same operations.

Programmable:  You can program sophisticated tests that 
bring out hidden information.

Comprehensive:  You can build a suite of tests that covers 
every feature in your Web site or application.

Reusable:  You can reuse tests on different versions of a 
Web site or application, even if the user interface changes.
